i have variable being used multiple threads, using synclock when getting , setting variable. wondering if can wrap synclock inside property, don't have type synclock statements every time use variable: private _obj new object public property obj() object synclock _obj return _obj end synclock end set(value object) synclock _obj _obj = value end synclock end set end property i unsure block, since end synclock statement after return statement. couldn't find online, wondering if i'm going wrong. thanks.

int inputnumber=0; int divisionstore=0,modstore=0; vector<int> mainvector; cout << "\nenter number convert binary.\n" << endl; cin >> inputnumber; { modstore=inputnumber%2; inputnumber=inputnumber/2; mainvector.push_back(modstore); }while(inputnumber!=1); (int i=0;i<mainvector.size();i++) { cout<<endl<<mainvector[i]<<endl; } seems there logical error cant find whats wrong it? program not print correct conversion seems loop ends before can push last number. i think need change: }while(inputnumber!=1) to: }while(inputnumber!=0)
